What is a corneal erosion?

Corneal erosion is a periodic breakdown of the outer layer of the cornea (the clear covering of the eye). It may result after a scratch or abrasion in the eye. An erosion may feel like a scratch causing tearing, foreign body sensation and light sensitivity. It may also happen more often after sleeping.

How are corneal erosions treated?

Corneal erosions can be treated several ways. Your ophthalmologist may recommend artificial tear drops or lubricating ointment, drops or ointment made of a salt solution, or wearing a contact lens to act as a bandage to the cornea. Sometimes a procedure may be performed to make micro-punctures in the outer layer of the cornea (called the epithelium) or the damaged epithelium may need to be removed. It is important not to rub your eyes while it is healing because the cells can easily be rubbed off. Keeping the eye well-lubricated can help keep erosions from recurring.
